In practice, I have found that n silikon,

even when complete,4 does not, when used alone, always give sntisiar-tory results forl the Purpose of removing surplus water from the thiatchun1her. In :i cmnptmion nppiicalin Serial No. thfr, tiled simuhaneotely herewith, I have shown the employment. in tho drainage-rhumIxer, of o .ipv additional to und sepuretri from the siplion. The prmt invention r-untmnplntes the. addition to the outrr t-ud ol' ai rmuplvto L phon, oa pipe ll constituting. sulvstnntizxily, u continuation of said sphou und having u swiveling couurrtiuu with tluhxtt'r so us not ten-interiore with the. svn-owing oft w nipnle, in the usual nwunvr, tuh lli" radiator. lar this purpose, the and o! tutoutnr ingof iiangcd and thut. part ot the ipv il therein housed may. hc provided with un annular enlargement, almrelq holding tlw-twu pipes in the le-sited relatnu without.

No mnt- 4 --I'l. to l-hc Siphon i", I regard as lu'ghly inx portant. especiallv when the pipe H is of arger diameter than the Siphon. In such event, the siphon apparently empties itself quite readily, and. the capillary action of the.. waiter in the Siphon is overcome.

In practice,4 and upon first use. of the deviee, stes-1n' enters (from the.' radiator) through ni-rple G, and, after passing through' drainage-c iambcr E, enters the Hoot-charnber b and esi-apre through )ort Y. The con# densation of steam in the i oat-chamber soon roduce's cnougl. water therein to raise theiloat U and ent olf the escape of steam through portA -The. heating of the airchamber a, dui-ing the operation aforesaid 'has rariiied lllcgnir in that chamber an( caused escape-.of some uir through opening b' and by waypof pori. Y. Upon a. subse- 4quent cooling of the device., the contraction of the air in'cihalnhcr-o drawsi water thereinto romthc"float-chamber, and the float` descends anda-gain opens port-Y, again permit-ting e.-ca. nc .of steam, u. 'consequent reheating of the nii-chamber, an expansion of I air t-lierciln'and transfer of water therefrom to the floatcha'mlxer and the lifting of' the oat and seating of the carried valve.

It frequentlg.r happens that a radiator,

4while velitingdisclmrgcs',water, and. under (from chamber b )lxack to the radiator and tcr how frequently water muy come to the valve, the latter \'ill inst-.only close tightly against leakage therethrough; and the instant' the water falls in the radiator, the Siphon alwavs automatically begins its work.
